You can do it with MS Paint. It's not the best way, but it's the most basic.
Open the image in Paint and go to "IMAGE" - "Attributes" - put the image size in the boxes and click "OK".
As far as how it looks.....I don't have a picture...I could go down and take one, but if you click on the link I posted above and scroll down to post #12 it will show you and explain better than I could.
Good luck. If you need any other help don't hesitate to ask. You could always send me the image and I could resize it for you.
